Premade teams are toxic for almost all soloque players.
Just about every premade I have come across is verbally toxic toward the soloque players on their team.
I queued up for a single /fsck'ing soloq game on NA and got placed with a Teemo and Draven who picked revive and ghost because they wanted to feed. Ten minutes in they were 0/11 and 0/13 respectively. I, any many many many other people want the option to make soloque an actual option.
GIVE US THE OPTION TO OPT OUT OF GETTING QUEUED WITH PREMADES.
